Holy bowties, Batman! Over the weekend Glee co-creator Ryan
Murphy tweeted a photo from the show's set of none other than Robin,
Batman's faithful sidekick, in the halls of McKinley High.

Judging by the bowtie, it seems that Blaine (Darren Criss) is the one in disguise, but what does it mean? Odds are good that this could be for season 4's Halloween episode. Last year we saw that Kurt and Blaine went out as Snooki and The Situation, respectively. Does this mean Kurt is Batman, or does Blaine have another Dark Knight?

Hopefully this is just one part of an all comic book or Batman-themed Halloween episode. I could easily see Brittany dressed as Catwoman (or, more specifically, Lord Tubbington). And I think Artie could make a decent Penguin. If the teachers get into it, Sue Sylvester would look amazing in a green track suit covered in question marks as the Riddler. "Riddle me this, glee club: You suck!"

What do you think of Robin on Glee? Is it definitely Blaine (the bowtie seems to be the giveaway)? Who will be his Batman? What other Glee Halloween costumes would you like to see?
